BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled canal block used for a canal, a sewer and a drain, a canal of a small river and the like.

[0002]

2. Description of the Related Art As this type of assembled waterway block, a construction method of laying bottom panels on a U-shaped frame (struts) simply by butting them has been conventionally used. Further, in a water channel block in which the bottom plate and both left and right side plates are supported and fixed by side plate support ridges provided on both side surfaces of the bottom plate, the side plate support ridges of the bottom plate form a step by projecting their upper parts outward. At the same time, a groove is formed in the lower portion, and the side plate is cut out below the inner surface of the side plate to form a mounting surface on the side plate supporting edge, a fitting contact surface to the step portion, and a fitting edge to the groove. , A water channel block in which the fitting contact surface is formed by a concave side surface and a convex side surface.
No. -15717) has been conventionally known.

However, the above-mentioned assembled water channel block in the prior art is one which is placed on a U-shaped frame and simply butted, and slips off, or the bottom of the water channel is thicker than the bottom panel. As a result, there was a problem that the water depth became shallow. Furthermore, in order to prevent slipping, when the bottom floor panel is concretely paved by simply butting it against the side of the U-shaped frame, the bottom floor panel is installed side by side.
When I tried to lift it for height adjustment, it was difficult to lift because it stuck to the muddy ground. In addition, even if it was lifted, soil adhered to the back surface of the bottom floor panel and had to be removed. In addition, the muddy ground caused uneven settlement of the bottom floor panel, and sediment deposited on it, impairing the function of the water channel. Further, in the conventional technique disclosed in Japanese Utility Model Publication No. 1-15717, the bottom plate and the left and right side plates are supported and fixed by side plate supporting edges provided on both side surfaces of the bottom plate to form a water channel block. The side plates have been devised, but the bottom plate has not been devised. The bottom between the U-shaped frame and the U-shaped frame was made by pouring ready-mixed concrete for concrete paving. For this reason, a curing period was required until the concrete hardened, and water could not flow immediately. Further, in a site where the groundwater level is high, once the fresh concrete is poured, water cannot escape from the bottom, so that there is a problem in that the fresh concrete must be poured while providing the drain holes. In view of the above circumstances, it is an object of the present invention to provide an assembled water channel block that allows easy and accurate horizontal maintenance when laying a bottom panel in consideration of preventing the water depth from becoming shallow. Is.

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and includes a U-shaped frame installed at a required interval along the longitudinal direction of a water channel, and between the U-shaped frames. In an assembled water channel block composed of a side wall panel set to support an end portion and a bottom floor panel, a receiving portion whose both sides are parallel to each other is formed, and the inner sides of both sides are raised.
A support member for a bottom floor panel, which is bent so as to cover the V-shaped frame, is placed on the U-shaped frame, and the bottom floor panel is arranged so as to engage with the receiving portions on both sides of the U-shaped frame. I adopted the technical means.

[0005]

The present invention, as a result of adopting the above technical means,
The depth of water does not become shallow, there is little risk of insufficient flow rate, and the support member is provided so that the bottom floor panel can be easily leveled, and since the bottom floor panel is soil, the weight of the bottom floor panel is low. Is supported by the receiving portion of the supporting member placed on the soil portion. Therefore, the strength of the receiving portion is almost unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. The embodiment shown in FIG. 1 is a schematic perspective view of an assembled waterway block showing an embodiment according to the present invention, in which 1 is a bottom panel and 2 is a U-shaped frame (having a column at both ends). ), 3 is a side wall panel, 4 is a support member,
This is the main element that constitutes the assembled waterway block. In addition, when the bottom floor panels 1 are arranged, a space between the bottom floor panels 1 may be about 2 cm, or may be arranged without being left. 2 and 3 are a side view and a plan view showing the shape of the support member 4. The length is variously determined depending on the size of the U-shaped frame 2. In an example of the shape, a flat portion 5 is formed by a metal plate so as to straddle the U-shaped frame 2, and the flat portion 5 is continuously formed.
Both sides are folded down, and further, the receiving parts 6 and 6 of the bottom laying panel 1 are formed by horizontally bending in opposite directions,
At one end, the rising column 8 of the U-shaped frame 2 (see FIG.
The cutout portion 7 is formed so as to avoid (see FIG. The cutouts 7 are provided only on the support members 4 located at the portions of the two upright supporting columns 8. In the case of the support members 4 located in the middle, the cutouts 7 are unnecessary. Further, as long as it does not hang up to the portions of the both upright supporting columns 8, the notch 7 may not be formed as shown in FIG. In this case, since the length of the receiving portion 6 becomes a little shorter, the receiving portions 6 supporting the bottom laying panels 1 on both sides are reduced, and thus the stability and the strength are somewhat inferior. However, there is almost no problem.
This is because the bottom is placed directly on the soil part of the ground. Also, I explained about the metal plate,
Needless to say, various materials such as concrete and reinforced plastic may be used instead of metal. However, in the case of concrete, the thickness must be increased to some extent from the viewpoint of production and strength, so the water depth becomes shallow and the required flow rate may be insufficient.
This can also be solved by considering the design. Especially in terms of strength,
Even if the thickness of the receiving portion 6 is thin, since the bottom portion of the bottom laying panel 1 is soil, the weight of the bottom laying panel 1 is supported by the soil portion and the receiving portion 6, so that the strength of the receiving portion 6 is almost unnecessary.

[0007]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) By arranging the bottom floor panels by using the support member, the horizontal floor and height of the bottom floor panels can be easily adjusted. (2) Since uneven settlement of the bottom floor panel does not occur, sediment does not accumulate, and even if sediment does accumulate, the top surface of the bottom floor panel is flat, so you can easily remove the soil with a scoop, etc. A stable supply of is maintained. (3) Since no ready-mixed concrete is used, no curing period is required, and water can flow immediately. (4) When the concrete pavement is done by pouring fresh concrete, the bottom of the waterway is completely sealed, but since the bottom floor panel is simply laid, groundwater flows into the waterway from the gap,
The groundwater level can be lowered. On the contrary, in the event of a flood, the effect of water permeating underground can be obtained.
